VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 451,822, dated May 5,1891.

Application filed January 26, 1891. Serial No. 379,076. (No model.)

To all whom it may concern.-

Be it known that I, ABIJAH F. HENRY, a citizen of the United States, anda resident of Vingate, in the county of Montgomery and State of Indiana,have invented certain new and useful Improvements in Vaporizers; and Ido hereby declare that the followingis a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to improvements in devices for applying medicines.

As is well known, many forms of diseases, especially of the throat andlungs, are now successfully treated by the vapor of certain medicalcompounds or preparations. These vapors, to effect the most beneficialresults, should be in a hot and moist condition when inhaled or appliedto the diseased parts; and the object of my invention, therefore, is toprovide an improved device whereby such vapors may be inhaled in a hotand moist condition by a patient.

The invention consists in the novel construction and combination ofparts hereinafter fully described, and specifically pointed out in theclaims.

In the accompany-ing drawings, Figure l is a central sectional view of adevice constructed in accordance with my invention when used as aninhaler. Fig. 2 is an elevation of the same adapted to have the vaporsapplied direct to the diseased parts.

In the said drawings the reference-numeral 1 designates a heater,consisting of a base, of any suitable material, made in two parts 2 and3, separated a short distance from each other and connected together bymeans of block 4, thus forming spaces for the passage of air to supportcombustion of the lamp or stove 5, which is inserted in a centralaperture in the part 2 and supported by the part 3. This aperture isslightly larger than the lamp or stove, so as to allow the air to enterthe chamber above, formed by the cylinder 7. This cylinder is made ofsheet metal and is provided with a jacket 8, of felt or other suitablematerial, to prevent radiation of heat.

The part 2 is provided with a series of up wardly-projectingspring-wires 9, which are surrounded by the lower end of the cylinderwhen the latter is in position, whereby it is prevented from lateraldisplacement.

The numeral 10 designates the vaporizer, comprising an inner and outervessel marked, respectively, 12 and 13. The outer vessel is providedwith a cover or top 14 and has a tube 15 extending to near the bottom ofthe vessel. It has another tube 16 extending therethrough and throughthe top or cover 17 of the inner vessel 12, the latter also beingprovided with a tube'lfi" extending from the top thereof to near thebottom and communicating with vessel 13. The periphery of the vessel 13at its top is provided with a series of hooks 18, which engage with theupper edge of the cylinder 7, so as to suspend the same therein abovethe lamp or heater.

The numeral 19 designates a hood made of muslin, linen, cotton, or othersuitable material, one end of which is connected with the top of thecylinder, while the other end is adapted to be held to the face of thepatient, surrounding the mouth and nose, and near the end connected withthe heater is provided a wire ring to prevent collapsing of the same.

The numeral 21 designates a bail, consisting of two vertical arms 22 anda hand-hold 23. The lower ends of these arms are secured to the base ofthe device and are at a distance to receive the cylinder 7 therebetween.They are also provided with spring-hooks consisting of spring-wires 24,secured at their lower ends to said arms and having their upper endsbent over into hooks 25, which engage with the top edge. of the cylinder7 and hold the same in place.

The operation is as follows: The vessel 13 is partly filled with waterthrough the tube 15, and a sufficient quantity of the medical compoundis poured into the vessel 12 through tube 16. The vaporizer is thensuspended by means of the hooks 18 on vessel 13 within the cylinder 7,the lamp 5 having been previously inserted in place and lighted. Theheat from the lamp will cause the Water in vessel 13 to boil and themedicine in the vessel 12 to be vaporized. The steam will now pass intovessel 12,

through pipe 16 and, mingling With the vapor contained therein, Willescape in ahot and moist condition through tube 16 into the hood 19 andbe conducted to the mouth and nostrils of the patient forinhalation. Incases where the vapors are to be applied direct to the diseased parts, Iremove the hood and apply to the tube 16 a rubber or other flexible hose26, with a nozzle 27, which is brought into close proximity with theparts to be subjected to the vapors. The tube 15 is provided with a hose28 and a bulb 29. WVhen tobe used it is placed in the heater, as beforeset forth, the nozzle 27 is applied to the parts to be treated and thesteam and vapors forced through the hose and nozzle by pressure upon theair-bulb. The nozzle can also be used for inhaling.

' From the above it will be seen that I provide a simple and effectivedevice whereby the vapors of medical compounds are applied in a veryefficient manner.

I do not confine myself to any particular description or character ofmedical compound or preparation to be employed, as it will vary with thenature of the disease to be treated.

By removing the hood and the flexible hose and placing a suitablepreparation in the inner or medicine vessel 12, the device may be usedfor disinfecting purposes. I may also dispense with the heater showninsome cases and vaporize the Water and medical compound by subjecting thevaporizer directly to the heat of a gas-flame or by any other meansfound convenient.

Having thus described my invention, what I claim is 1. A vaporizerconsisting of an outer closed vessel having a tube extending throughthe.

top to near the bottom thereof, an inner vessel suspended within saidouter vessel, a tube passing through the tops of said vessels, and atube extending through the top of said inner vessel to near the bottomthereofand communicating with the outer vessel, in combination with acasing within which said vaporizer is suspended, and a heater,substantially as described.

2. The combination, with the heater comprising the base 1, adapted toreceive a lamp or stove, and the cylinder 7 connected therewith, of avaporizer suspended Within said cylinder, consisting of the inner andouter closed vessels 12 and 13, the tubes 15, 16, and 16, and the hood19, connected with said cylinder and adapted to be applied to the faceof a patient, substantially as described.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two Witnesses.
